The hardening of the sandblasted surface retards the crack nucleation, enhances the resistance to plastic deformation and improves the stress distribution, thus providing the ability to resist to crack propagation.
WHY HARDEN BALL PINS ARE USED WITH CARBON FIBRE BEARINGS?
Vehicle manufacturers sometimes harden ball pins for applications where the ball pin neck can be subjected to very high forces e.g. high speed braking or where the vehicle can be heavily loaded. Hardening increases fatigue resistance and increases durability.
It’s normal for your car to vibrate slightly when you’re driving thanks to the rotation of the crankshaft and other moving parts in your engine. But, when these vibrations feel more like shaking, it’s time to investigate why.
It’s a proven fact that potholes can damage your car – even if you react in time to partially avoid them. And, while some damage is immediately visible, it might take you a while to notice that your car isn’t handling as well as it used to.
While there are several types of steering systems on the market, the two main ones are recirculating ball steering, which is mostly used for heavy vehicles, and rack and pinion steering, which is common for cars.
